No. It is brass with a 24K gold plating, not solid gold. The plating gives the color, but it is a thin layer that can wear off.

Will it turn my skin green?

It can. Brass reacts with sweat and oils on some people and leaves a green mark. Keeping it dry and cleaning it after wear reduces the chance.

What length is it, and can I wear a pendant on it?

It is 18 inches long, which sits at the collarbone. The link chain can hold a light pendant, but heavy pendants may stretch the links.

How should I care for it?

Keep it away from water, perfume and lotion, and wipe it with a soft cloth after wearing. Store it in a dry pouch to slow tarnishing.

Is it worth buying over a solid gold chain?

If you want the gold look for occasional wear, yes, at a fraction of the cost. If you want something that lasts for years, solid gold or gold-filled is the better buy.
